Firstly, this paper defines the basic theory of human resource management, and then in Lenovo case, this paper focused on analyzing Lenovo＇s acquisition of IBM＇s PC business, analyzed the condition of Lenovo PC business and mobile Intemet business by using traditional Boston matrix, and concluded that effect of Lenovo acquisition is not significant, then put forward some improving measures.展开更多

In fact, this concept is a generalized concept of the quasi-coincidence of a fuzzy point in a fuzzy set. By using this new concept, the authors define the notion of interval valued （∈, ∈ Vq）fuzzy h-ideals of hemirings and study their related properties. In addition, the authors also extend the concept of a fuzzy subgroup with thresholds to the concept of an interval valued fuzzy h-ideal with thresholds in hemirings.展开更多

We study the double derivation algebra 7）（g） and describe the relation between 7）（9） and the usual derivation Lie superalgebra Der（9）. We show that the set 7）（9） of all double derivations is a subalgebra of the general linear Lie superalgebra gl（9） and the inner derivation algebra ad（9） is an ideal of 7）（9）. We also show that if 9 is a perfect n-Lie superalgebra with certain constraints on the base field, then the centralizer of ad（9） in 7P（9） is trivial. Finally, we give that for every perfect n-Lie superalgebra 9, the triple derivations of the derivation algebra Der（9） are exactly the derivations of Der（9）.展开更多
